Abstract

Abstract: Based on the FEKO (Feldberechnung bei Korpern mit beliebiger Oberflache) products,the strength of the high-altitude meteorological radar field was simulated.The discrete values of its relative field strength were obtained.Five kinds of interpolation methods,including the bilinear interpolation method,the inverse distance weighted method with k=1 and 2,respectively,and the inverse distance weighted method based on an edge-smoothness with k=1 and 2,respectively,to calculate the relative field strength of high-altitude meteorological radar in any directions were compared.The results show that at any azimuth and zenith angles,the bilinear interpolation method performs the best results.Under the condition that the initial field strength is at intervals equal or less than 0.5 degree in the main lobe and equal or less than 0.1 in the side lobe,its simulation results can meet the needs of the meteorological radar to simulate a training system.
